Size a hospital's revenue and EBITDA from its beds, then value a new wing at maturity against what it costs to build.

Anvika earns Rs 511 crore of revenue and Rs 112.4 crore of EBITDA; the wing earns Rs 237 crore of revenue and Rs 42.7 crore of EBITDA at maturity, worth Rs 769 crore at 18x against Rs 400 crore of cost. On paper the wing creates about Rs 369 crore of value, but only if it fills: it is worth its cost at 34% occupancy, and the three-year ramp plus Rs 36 crore a year of interest on the build cost is where the risk sits.

A hotel with 100 rooms does not earn on 100 rooms; it earns on the rooms with a guest in them, at the rate each guest pays. Hospital revenue is beds times occupancy times revenue per occupied bed per day times days, so Anvika's 400 beds at 70% are 280 occupied beds, which at Rs 50,000 a day for 365 days earn Rs 511 crore. At a 22% margin that is Rs 112.4 crore of EBITDA. The average revenue per occupied bedTotal hospital revenue divided by occupied bed days; the hospital equivalent of a hotel room rate, driven by case mix, speciality and pricing. is the number healthcare bankers watch, because it carries the case mix: a cardiac bed earns several times a general ward bed.

Run the same four drivers. 200 beds at 65% is 130 occupied beds, Rs 237 crore of revenue, and at an 18% margin Rs 42.7 crore of EBITDA, worth Rs 769 crore at 18x: Rs 3.84 crore a bed against Rs 2 crore a bed to build. That gap, about Rs 369 crore, is the case for building. But it rests on three things the hospital does not fully control: that the wing reaches 65%, that it does so by year 3, and that an 18x multiple still applies to a chain with more leverage. Work the first one backwards: the wing is worth exactly its cost when EBITDA is Rs 22.2 crore, which needs occupancy of about 34%. Below that, Anvika has spent Rs 400 crore to create less than Rs 400 crore of value.

Ramp is the risk, and interest makes it bite. In year 1 the wing might run at 35% occupancy, Rs 128 crore of revenue, while carrying a full staff and Rs 36 crore a year of interest if the Rs 400 crore is borrowed at 9%, so the wing loses money for two years before it earns the Rs 42.7 crore the valuation assumes. The group's EBITDA of Rs 112.4 crore can absorb that, which is why a 400-bed hospital can build a 200-bed wing and a 100-bed one cannot. Present it as: current numbers, the wing at maturity, the value against cost, then the two sensitivities that matter, occupancy at maturity and the year it is reached. The limit: the 18x multiple is for a listed chain with a track record; a single hospital adding a wing does not get that multiple on the wing alone, and the honest number for the wing is the multiple a buyer would pay for Anvika as a whole with the wing full.
